Title: Improvements relating to the control of micro organisms
IPC: B65D81/28
Filed: 1965-08-19
Abstract: The invention comprises acylated alpha hydroxy carboxylic acids, and salts thereof, of the formula <FORM:1115480/C2/1> where RCO is an acyl radical of a fatty acid having 8-12 carbon atoms, each of A and B are a hydrogen atom or a methyl group, Y is a cation, x as an average is a number from 0.3 to 6, n is an integer equal to the valency of the cation Y and m is a number from 1 to n, except that when A is hydrogen and B is methyl and Y is sodium, RCO cannot be lauroyl.  Salts of the acylated alpha hydroxy carboxylic acids are prepared by heating the appropriate fatty acid with the alpha hydroxy carboxylic acid in the presence of more than a catalytic amount of a basic reacting alkali metal or alkaline earth metal compound. Acidification of the product with dilute mineral acid gives the corresponding free acid product.  The products are used as fungicides and bactericides.ALSO:Foodstuffs are protected against the growth of undesired micro-organisms by incorporating into the foodstuff, or coating the foodstuff with an acylated product of an alpha-hydroxy carboxylic acid of the formula:  <FORM:1115480/A1-A3/1> wherein RCO is an acyl radical of a fatty acid having from 8 to 12 carbon atoms, A and B are each a hydrogen atom or a methyl group, Y is a cation, x as an average is a number between 0.3 and 6, n is an integer equal to the valency of the cation Y and m is a number of from 1 to n, in the form of a non-toxic acid or salt.  In the examples, (a) calcium capryl-2 lactylate is incorporated as a bactericide in a custard pie filling and (b) baked dinner rolls are dipped in an ethanol solution of calcium capryl-2 lactylate to prevent mould formation.ALSO:Bactericidal and fungicidal compositions, including pharmaceutical compositions for topical application comprise an acylated alphahydroxy carboxylic acid of fomula: <FORM:1115480/A5-A6/1> wherein RCO is an acyl radical of a fatty acid having from 8 to 12 carbon atoms, A and B are each a hydrogen atom or a methyl group, Y is a cation, x as an average is a number between 0.3 and 6, n is an integer equal to the valency of the cation Y and m is a number of from 1 to n, in admixture with a diluent or carrier. The phamaceutical composition may be in the form of dusting powders, ointments, salvers or solutions.

Title: Improvements in or relating to electric summating apparatus
IPC: G08C13/02
Filed: 1935-12-28
Abstract: 468,040. Counting-apparatus. RUTHER. FORD, J. G., and WARREN, T. R. Dec. 28, 1935, No. 35885. [Class 106 (i)] In a system for summating impulses from several sources, each source has associated impulse and resetting relays interconnected so that impulses from the sources may be transmitted to a counter over a common circuit without interference. As shown in the Figure impulse sources A ... D, e.g. electricity meters, are adapted to operate corresponding impulse relays E<1> ... E<4> over corridor circuits 3, 4 which are opened upon each operation of the impulse relays by resetting relays Fl ... F4 connected in parallel across the circuit 17 of a common counter 18. When the contact 1 of a source changes over, relay E is operated to isolate other sources at contacts 9, 10 and to close the counting circuit over the corresponding relay F which operates its contacts 5 to release the impulse relay and then allow the counting of impulses from other sources if they are in an operative condition. In a modification, provision is made for counting impulses of opposite polarity and having opposite additive effects on the counter. In this arrangement, an additional accumulator switch is provided which when positive impulses are received remains in a limit position to connect up the counter. Upon receipt of negative impulses the switch is operated in the opposite direction and the counter is disconnected. The counter is again connected only when the effect of the received negative impulses is nullified by further positive impulses. The stepping of the switch may be effected by relays and a thermal relay may be provided which is operated to disconnect the supply in the event that the counter circuit is closed for a time longer than the normal time period of an impulse. The counter may be located at a distance and operated by wireless.

Title: Improvements in and relating to tape recording and/or reproducing devices
IPC: G11B15/70
Filed: 1954-12-14
Abstract: 770,348. Magnetic tape recording and/or reproducing devices. LOGOTHETOPOULOS, J. N. Dec. 14, 1954, No. 36179/54. Class 40 (2). [Also in Group XXIV] In a magnetic tape-recording and/or reproducing device comprising coaxial rotatable tape supply and winding spools 14, 10 between which a magnetic tape 21 is driven by a motor 1, the tape is guided by members 19, 6 and by magnetic erasing and recording or reproducing heads 22, 23 by which the tape in its travel changes its plane from that of one spool to that of the other by making two 90 degree twists, respectively between the member 19 and the head 22 and between the head 23 and the member 6, and is vertically displaced between the two heads by a distance corresponding to that between the supporting surfaces of the two spools. As shown, the tape, which may be a ferromagnetic sound tape, is fed, by the member 6 which is a tape transporting shaft driven by the motor 1, over the guide roller 19 which is displaceable in the direction shown by the arrow so as to selectively couple with the heads a plurality of juxtaposed sound tracks on the tape. The tape then passes over the head 22 and under the head 23, whose air gaps are arranged appropriately, and over the shaft 6 against which it is pressed by a roller 24. Drive between the motor 1 and shaft 6 is conveyed by a rubber rope 5 which by a member 26 may be moved down to engage other diameters of the pulleys to produce a lower tape speed which may be used for recording speech. To effect tape rewinding a plate 16 on which the roller 24 is mounted is pivoted clockwise about a pin 17 whereby the roller 24 is moved from the tape and a roller 18 engages the tape to move it free of the shaft 6, and the motor 1 is pivoted by an operating member 28 about a pin 3 in a frame whereby a friction driving annulus 11 on the motor shaft engages a disc 12 mounted on a shaft 13 to which by a nut 15 is fixed the supply spool 14 which is thereby driven backwardly. During forward tape running the hollow shaft 9, which may be of nylon, of the winding spool 10 is driven by the motor via a metal resilient rope 8. The member 28 is a vertical lever displaceable into three positions in a base-plate slit 29 which positions correspond to recording or reproduction as shown, an intermediate non- driving position, and back-winding. The two spools rotate in opposite directions to increase the friction between their shafts to facilitate tensioning the tape. The head 23 may be replaced by separate recording and reproducing heads, and there may be provided a cathoderay indicator 27 to check the operation of an amplifier not shown in the device and, covering the base-plate 30, a lid not shown having attached thereto a loud-speaker.
